A music recommendation site with an incredibly cool navigation system. I thought the relationships it showed were fairly accurate, but it's more fun just to enter something and start clicking around.

Neat site. Most of the correlations make sense but some were way off, i.e. Big Head Todd and THe MOnsters next to Radiohead........uh......no. :)

Interesting, but Jethro Tull immediately next to Gary Numan?! I don't think so.
